I am starting a project to use the labjack to log / graph data from some loadcells and am able to use the LJTIA to get the differential signals into one AIN channel.
The problem I'm not sure on the best solution to is displaying the data to a panel meter so that the camera watching the test has the load displayed AND I'm logging/graphing the load on a computer.
What would be the best way to send data from the load cell to both the labjack and a panel meter?

The likely solution seems to have the computer monitor near the test specimen so it shows up in the video.
As for a standalone meter of some sort, find some of interest and post links to electrical details and we will check them out.
I too am looking for a way to display via a panel meter, but for a different reason.
We run tests overnight and on weekends, and when a laptop is performing the controller functions, then the entire system is dependent upon Windows behavior (stopping our execution to perform Windows updates overnight). When Windows interrupts, it sets back testing, and we are an R&D facility, so those interruptions are not acceptable.
If the LabJack T7-Pro performs the controller functions, then we are immune to Windows updates, but I don't know how to display current state values like test cycle count and current load cell reading on a laptop, so we would have to run blind. (I am a newbie, maybe it's possible). The T7-Pro has ethernet and wi-fi, but finding an appropriate panel meter to use it has not happened yet.
I would say that with some attention to settings, Windows can be made to run very reliably for a long time. Years ago that was not the case, but that it my observation in the last 10 years.
Nonetheless, it sounds like you are thinking you would write a Lua script that runs on the T7-Pro and does your controller functions. At the same time you can have a computer reading & displaying values like cycle count and load from the T7-Pro. If the computer is working you have your display. If the computer is not working you don't have your display but the Lua script on the T7-Pro is still doing what you want. Sounds like a great application for Lua scripting. Tell us more about your controller functions and we can see if it sounds like something that can fit in a Lua script on a T7-Pro.
Realize that the computer displaying your values can be anything running Linux/Mac/Windows (e.g. Raspberry Pi) or even just anything cable of acting as a Modbus TCP client (e.g. PLC).
